Message

I build and deliver full-stack SaaS platforms for clients including CarRental8 and Auto Europe, covering logistics, warehousing, booking, and reporting tools.

My React, Laravel, and MySQL applications support more than 2,500 daily bookings and transactions at 99% uptime. I integrate Stripe and Worldline payments and deploy scalable applications through Laravel Vapor.

Previously at ITEL International, I built a Workforce Application supporting 1,200+ employees and established a Web HRM application for core HR workflows. At Innovate Software NL, I redeveloped courier and warehouse systems for Knutsford Express and shipped React Native mobile applications.

Across two decades of web and mobile delivery, I’ve worked with React, React Native, Laravel, .NET, Azure, AWS, CI/CD, and automated testing. I use Claude and Codex pragmatically to accelerate delivery while maintaining code quality.
